Description
Die Erfindung betrifft ein Verfahren zur Ansteuerung einer leistungsverzweigten Getriebevorrichtung, insbesondere in einem Fahrzeug, wobei die Getriebevorrichtung einen elektrischen Variator und ein Getriebe mit verstellbarer Übersetzung umfasst, um einen Antriebsmotor mit einem Fahrantrieb des Fahrzeugs zu verbinden undwobei der elektrische Variator ein Summierungsgetriebe, zumindest eine erste und zumindest eine zweite elektrische Maschine und eine Steuerung der elektrischen Maschinen zum stufenlosen Variieren einer Übersetzung des Summierungsgetriebes umfasst.The invention relates to a method for controlling a power-split transmission device, in particular in a vehicle, wherein the transmission device comprises an electric variator and a transmission with adjustable ratio to connect a drive motor with a drive of the vehicle and the electric variator a summation, at least a first and at least a second electric machine and a controller of the electric machines for continuously varying a ratio of the summation gear comprises.
Stufenlos leistungsverzweigte Getriebevorrichtungen sind in Baumaschinen und landwirtschaftlichen Arbeitsmaschinen, beispielsweise Traktoren, nach heutigem Stand der Technik insbesondere häufig im Premiumsegment anzutreffen und als hydraulisch-mechanisch leistungsverzweigte Getriebe ausgeführt. Der Leistungsfluss teilt sich hierbei in einen mechanischen Pfad, regelmäßig über einen oder mehrere Planetenradsätze geführt, und in einen hydrostatischen Pfad auf, in dem die Leistung über einen hydrostatischen Variator geführt wird, mit dem eine stufenlose Einstellung der Übersetzung vorgenommen werden kann. Am Markt erhältlich sind derartige Getriebevorrichtungen beispielsweise von Herstellern wie John Deere oder Fendt.Infinitely power-split transmission devices are found in construction machinery and agricultural machinery, such as tractors, according to the current state of the art in particular often in the premium segment and designed as a hydraulic-mechanical power-split transmission. The power flow is divided here into a mechanical path, regularly guided over one or more planetary gear sets, and in a hydrostatic path, in which the power is passed through a hydrostatic variator, with a stepless adjustment of the translation can be made. Such transmission devices are available on the market from, for example, manufacturers such as John Deere or Fendt.

Eine andere Entwicklungsrichtung bei Baumaschinen und landwirtschaftlichen Arbeitsfahrzeugen besteht in dem Aufbau eines zu dem bestehenden Bordnetz der Maschine zusätzlichen und mit einer höheren Nennspannung betriebenen zweiten Bordnetzes, mit dem elektrische Verbraucher, die eine derart höhere Nennspannung für ihren Betrieb benötigen, angetrieben werden können. Diese elektrischen Verbraucher können sowohl auf der Maschine an sich als auch auf einem Anbaugerät angeordnet sein. Herkömmlicherweise wird dieses zusätzliche zweite Bordnetz auf der Maschine durch ein eigenes dafür vorgesehenes Generatorsystem erzeugt. Hierbei entstehen allerdings zusätzliche Produktkosten und es reduziert sich der Gesamtwirkungsgrad infolge der zusätzlichen Bauteile.Another development direction in construction machinery and agricultural work vehicles is the construction of a to the existing electrical system of the machine additional and operated with a higher nominal voltage second electrical system, with the electrical consumers who need such a higher rated voltage for their operation, can be driven. These electrical consumers can be arranged both on the machine itself and on an attachment. Conventionally, this additional second electrical system is generated on the machine by a dedicated dedicated generator system. This, however, additional product costs and it reduces the overall efficiency due to the additional components.
Ausgehend hiervon besteht die Aufgabe der vorliegenden Erfindung darin, ein Verfahren anzugeben, mit dem ein zweites Bordnetz auf dem Fahrzeug in integrierter Weise gespeist werden kann.Proceeding from this, the object of the present invention is to provide a method with which a second electrical system can be powered on the vehicle in an integrated manner.
Die Aufgabe wird gelöst durch ein Verfahren nach dem Oberbegriff des Anspruchs 1, bei dem erfindungsgemäß bei Erkennen einer externen Leistungsanforderung eines elektrischen Verbrauchers ein Übersetzungsbereich des Getriebe mit verstellbarer Übersetzung derart eingestellt wird, dass die zweite elektrische Maschine generatorisch und die erste elektrische Maschine derart betrieben wird, dass eine bezogen auf die externe Leistungsanforderung bestehende Leistungsunterdeckung oder Leistungsüberdeckung kompensiert wird.The object is achieved by a method according to the preamble of
Die erste elektrische Maschine kann bevorzugterweise spannungsgeregelt betrieben werden. Hierdurch wird die für die Regulierung eines Gleichstromzwischenkreises erforderliche elektrische Leistung produziert oder verbraucht. Die zweite elektrische Maschine kann drehzahlgeregelt betrieben werden. Hierdurch wird die elektrische Leistung produziert oder verbraucht, um abhängig von der aktuell herrschenden Traktionsanforderung des Fahrzeugs über die Drehzahl der zweiten elektrischen Maschine die Übersetzung des Summierungsgetriebes einzustellen. Als Kogeneration soll nun ein Zustand bezeichnet werden, in dem beide elektrische Maschinen generatorisch betrieben werden. Unter externer Leistungsanforderung wird in diesem Kontext eine Leistungsanforderung verstanden, die außerhalb der Getriebevorrichtung entsteht. Somit kann die externe Leistungsanforderung beispielsweise von einem auf dem Arbeitsfahrzeug angeordneten elektrischen Verbraucher oder von einem auf einem Anbaugerät des Arbeitsfahrzeugs angeordneten elektrischen Verbraucher stammen.The first electrical machine can preferably be operated under voltage control. As a result, the required for the regulation of a DC link electrical power is produced or consumed. The second electric machine can be operated speed-controlled. As a result, the electrical power is produced or consumed in order to adjust the ratio of the summation gearbox depending on the currently prevailing traction requirement of the vehicle on the speed of the second electric machine. The cogeneration is now a state in which both electrical machines are operated as a generator. In this context, external power requirement is understood to mean a power requirement which arises outside the transmission device. Thus, the external power demand may originate, for example, from an electrical load arranged on the work vehicle or from an electrical load arranged on an attachment of the work vehicle.
Unter einer Leistungsunterdeckung bzw. Leistungsüberdeckung wird in diesem Kontext eine Differenz zwischen der von den beiden elektrischen Maschinen oder nur einer der elektrischen Maschinen erzeugten elektrischen Leistung und der Höhe der externen Leistungsanforderung dahingehend verstanden, dass eine Unterdeckung vorliegt, wenn die externe Leistungsanforderung die erzeugte elektrische Leistung übersteigt, und dass eine Überdeckung vorliegt, wenn die erzeugte elektrische Leistung die externe Leistungsanforderung übersteigt. Power undercapacity in this context is understood as meaning a difference between the electric power generated by the two electric machines or only one of the electric machines and the level of the external power request that there is a shortage when the external power demand is the generated electric power exceeds, and that an overlap exists when the generated electric power exceeds the external power requirement.
Es kann der Fall auftreten, dass die zweite elektrische Maschine eine elektrische Leistung in einer bestimmten Höhe erzeugt, aber ein höherer externer Leistungsbedarf besteht. Um diese Differenz zumindest teilweise zu kompensieren kann die erste elektrische Maschine ebenfalls generatorisch betrieben werden. Es kann andererseits der Fall auftreten, dass die zweite elektrische Maschine eine elektrische Leistung in einer bestimmten Höhe erzeugt, aber ein niedrigerer externer Leistungsbedarf besteht. Um diese Differenz, die dann einen Leistungsüberschuss darstellt, zu kompensieren, wird die erste elektrische Maschine motorisch betrieben, um diesen Leistungsüberschuss aufzunehmen und als Blindleistung in das Summierungsgetriebe zurückzuführen.It may be the case that the second electric machine generates electric power at a certain level but has a higher external power demand. To compensate for this difference at least partially, the first electric machine can also be operated as a generator. On the other hand, it may be the case that the second electric machine generates electric power at a certain level but has a lower external power requirement. In order to compensate for this difference, which then represents a power surplus, the first electric machine is operated by a motor to absorb this power surplus and return it to the summation gear as reactive power.
Erfindungsgemäß ist nun erkannt worden, dass eine im Variatorzweig entgegen der ursprünglichen Richtung fließende Blindleistung zur Deckung einer externen Leistungsanforderung herangezogen werden kann. Hierzu kann gezielt ein solcher Übersetzungsbereich des Getriebes mit verstellbarer Übersetzung eingestellt werden, dass das Summierungsgetriebe eine Leistung in den Variatorzweig hinein abgibt. Diese in den Variatorzweig abgegebene Leistung wird nicht als Blindleistung in das Summierungsgetriebe zurückgeführt, da sie erfindungsgemäß über die zweite elektrische Maschine und über die Steuerung als elektrische Leistung zur Deckung der externen Leistungsanforderung abgeführt wird. Wenn die externe Leistungsanforderung nicht von der zweiten elektrischen Maschine alleine gedeckt werden kann, kann auch die erste elektrische Maschine generatorisch betrieben werden, so dass beide elektrische Maschinen im Sinne der Kogeneration betrieben werden. Der Vorteil dieses Betriebsmodus besteht darin, dass mittels zweier elektrischer Maschinen ein externer Leistungsbedarfs gedeckt werden kann, so dass das Leistungsniveau jeder einzelnen Maschine und der entsprechenden Elektronik reduziert werden kann.According to the invention, it has now been recognized that reactive power flowing in the variator branch opposite to the original direction can be used to cover an external power requirement. For this purpose, such a transmission range of the transmission can be adjusted with adjustable translation specifically that the summation outputs a power in the variator in it. This output in the variator branch power is not returned as reactive power in the summation, since it is discharged according to the invention via the second electric machine and the controller as electrical power to cover the external power requirement. If the external power requirement can not be covered by the second electric machine alone, the first electric machine can also be operated as a generator, so that both electric machines are operated in the sense of cogeneration. The advantage of this mode of operation is that by means of two electrical machines, an external power demand can be met, so that the performance level of each machine and the corresponding electronics can be reduced.
Bevorzugt wird das Summierungsgetriebe durch ein Planetenradgetriebe mit drei Antriebsschnittstellen gebildet, wobei je nach Richtung des Leistungsflusses die Antriebsschnittstellen als Eingang oder als Ausgang des Planetenradgetriebes wirken können. Es kann vorgesehen sein, dass der Antriebsmotor mit der ersten Antriebsschnittstelle des Planetenradgetriebes antriebsverbunden ist, um die Getriebevorrichtung mit Antriebsleistung zu versorgen, die wiederum über das mit der zweiten Antriebsschnittstelle des Planetenradgetriebes verbundene Getriebe mit verstellbarer Übersetzung an den Fahrantrieb weitergegeben werden kann. Weiterhin kann vorgesehen sein, dass die zweite der beiden elektrischen Maschinen mit der dritten Antriebsschnittstelle des Planetenradgetriebes antriebsverbunden ist, um eine variable Übersetzung zwischen der ersten Antriebsschnittstelle und der zweiten Antriebsschnittstelle des Planetenradgetriebes darzustellen. Bevorzugt ist die zweite der beiden elektrischen Maschinen mit dem Antriebsmotor des Arbeitsfahrzeugs antriebsverbunden, wobei dies unter Zwischenschaltung einer Übersetzung in Form einer Stirnradstufe erfolgen kann.Preferably, the summation gear is formed by a planetary gear with three drive interfaces, depending on the direction of the power flow, the drive interfaces can act as an input or output of the planetary gear. It can be provided that the drive motor is drive-connected to the first drive interface of the planetary gear, in order to supply drive power to the transmission device, which in turn can be passed to the traction drive via the transmission with adjustable ratio connected to the second drive interface of the planetary gear. Furthermore, it can be provided that the second of the two electrical machines is drive-connected to the third drive interface of the planetary gear in order to represent a variable ratio between the first drive interface and the second drive interface of the planetary gear. Preferably, the second of the two electric machines is drive-connected to the drive motor of the working vehicle, wherein this can be done with the interposition of a translation in the form of a spur gear.
Während des Antriebs der Arbeitsmaschine durch den Antriebsmotor kann die zweite elektrische Maschine im Generatorbetrieb und im Motorbetrieb betrieben werden. Der Generatorbetrieb erzeugt elektrische Leistung, die per Definition mit einem negativen Vorzeichen versehen ist, und der Motorbetrieb benötigt bzw. verbraucht elektrische Leistung. Der Leistungsbedarf im Motorbetrieb beziehungsweise die Leistungsabgabe im Generatorbetrieb der zweiten elektrischen Maschine ist abhängig von der erforderlichen Zugkraft des Arbeitsfahrzeugs und der nötigen Drehzahl der zweiten elektrischen Maschine, um das einzustellende Übersetzungsverhältnis des Planetenradgetriebes zu erreichen.During the drive of the working machine by the drive motor, the second electric machine can be operated in generator mode and in engine mode. The generator operation generates electrical power that is by definition given a negative sign and the motor operation consumes or consumes electrical power. The power requirement in engine operation or the power output in generator operation of the second electric machine is dependent on the required tractive force of the work vehicle and the required speed of the second electric machine to achieve the set ratio of the planetary gear.
Im Fall einer externen Leistungsanforderung kann ein Übersetzungsbereich des Getriebes mit verstellbarer Übersetzung gewählt werden, so dass die zweite elektrische Maschine im Generatorbetrieb betrieben wird. Die von der zweiten elektrischen Maschine im Generatorbetrieb abgegebene elektrische Leistung kann über die Steuerung einem externen elektrischen Verbraucher zur Verfügung gestellt, um einen bestehenden externen Leistungsbedarf zu decken. Insgesamt steigt durch das erfindungsgemäße Getriebesteuerverfahren der an der Ausgangswelle und der Steuerung der Getriebevorrichtung erzielte Gesamtwirkungsgrad, da die elektrische Leistung der zweiten Maschine zur Erfüllung von Zugkrafterfordernissen ohnehin erzeugt werden muss. Der Vorteil besteht nun darin, dass diese elektrische Leistung nicht als Blindleistung über den Variatorzweig wieder in das Planetenradgetriebe eingespeist wird, sondern über die Steuerung einem externen elektrischen Verbraucher zur Verfügung gestellt wird.In the case of an external power demand, a gear ratio range of the variable speed gearbox can be selected so that the second electric machine operates in generator mode. The electrical power output by the second electrical machine during generator operation may be provided by the controller to an external electrical load to meet an existing external power demand. Overall, increases the achieved by the transmission control method according to the invention on the output shaft and the control of the transmission device overall efficiency, since the electrical power of the second machine to meet Zugkrafterfordernissen must be generated anyway. The advantage consists in the fact that this electrical power is not fed back into the planetary gear as reactive power via the variator branch, but is made available to an external electrical load via the control.
Bevorzugt wird eine Übersetzung des Getriebes unter Berücksichtigung eines Fahrwiderstandes, der externen Leistungsanforderung und eines Fahrgeschwindigkeitswunsches eingestellt. Hierdurch wird sichergestellt, dass ein Übersetzungsbereich des Getriebes mit verstellbarer Übersetzung nur dann angesteuert wird bzw. nur dann ein anderer als der vorliegende Übersetzungsbereich angesteuert wird, wenn der momentan herrschende Fahrwiderstand und die Fahrgeschwindigkeit dies erlauben.Preferably, a ratio of the transmission is set in consideration of a running resistance, the external power demand, and a travel speed request. This ensures that a transmission range of the transmission with adjustable ratio is only then controlled or only a different than the present transmission range is controlled when the currently prevailing driving resistance and the driving speed allow this.
Bevorzugt ist ein mit der Steuerung verbundener Energiespeicher vorgesehen, um eine bezogen auf die externe Leistungsanforderung bestehende Leistungsüberdeckung oder Leistungsunterdeckung zu kompensieren. Hierdurch ist gewährleistet, dass im Falle einer Leistungsüberdeckung nochmals weniger Leistung als Blindleistung zirkuliert und im Falle einer Leistungsunterdeckung kann aus dem Energiespeicher Leistung zugesteuert werden.Preferably, an energy store connected to the controller is provided in order to compensate for an existing power coverage or power shortage based on the external power request. This ensures that, in the case of a power overlap, even less power circulates than reactive power, and in the case of a power shortage, power can be supplied from the energy store.
Bevorzugt erfolgt über die Steuerung eine Drehmomentverstellung der elektrischen Maschinen unabhängig von der Drehzahl der elektrischen Maschinen, um Energie in jede der elektrischen Maschinen oder einen Energiespeicher zu speisen und jede der beiden elektrischen Maschinen generatorisch zu betreiben.Preferably, the control is a torque adjustment of the electric machines, regardless of the speed of the electric machines to power energy in each of the electrical machines or an energy storage and operate each of the two electric machines as a generator.
